Long-term oncologic outcome of D3 lymph node dissection for clinical stage 2/3 right-sided colon cancer.

Purpose: To investigate oncologic outcomes including overall survival and disease-free survival depending on the extent of lymphadenectomy (D3 versus D2) by comparing D3 and D2 lymphadenectomy in patients with clinical stage 2/3 right colon cancer.

Methods: Consecutive series of patients who underwent radical resection for right colon cancer at our three hospitals between January 2015 and June 2018 were retrospectively analyzed. Study cohorts were divided into two groups: D3 group and D2 group.

Endoscopic Stenting for Malignant Left-Sided Large-Bowel Obstruction in Patients with Colorectal Cancer: Evaluation according to Pathological Stage.

Introduction: Self-expandable metallic stents (SEMSs) are widely used in patients with malignant left-sided large-bowel obstruction (MLLO) to convert an emergency situation into an elective one. However, the effects of endoscopic stenting on oncological outcomes remain unclear. This study aimed to analyze the oncological outcomes of SEMS placement in patients with MLLO stratified by pathological stage.

Clinical Significance of Surgical Resection Timing from Endoscopic Stenting for Left-Sided Large-Bowel Obstruction in Colorectal Cancer.

Background: The optimal interval between self-expanding metallic stent (SEMS) insertion and surgery remains controversial in malignant left-sided large-bowel obstruction (MLLO), especially with respect to oncologic aspects.

Aims: The aim of this study is to examine whether the time interval to surgery is related to oncologic outcomes.

Methods: Prospectively collected database of MLLO between January 2005 and December 2017 were reviewed.

Clinical Implications of Combined Lymphocyte and Neutrophil Count in Locally Advanced Rectal Cancer After Preoperative Chemoradiotherapy.

Background: There are controversies about the ability of neutrophil to lymphocyte ratio to predict the recurrence and survival in patients with locally advanced rectal cancer (LARC) treated with neoadjuvant chemoradiation. The objective of this study is to investigate the prognostic potential of combined lymphocyte count (LC) and neutrophil count (NC) in LARC patients treated with chemoradiotherapy (CRT) followed by curative surgery.

Methods: Patients with LARC who underwent surgical resection between January 2010 and December 2017 were reviewed retrospectively.

Prognostic Reappraisal of Postoperative Carcinoembryonic Antigen in T1-2N0 Colorectal Cancer.

Background/aim: The purpose of this study was to compare the prognostic value of preoperative carcinoembryonic antigen (CEA), preoperative CEA/tumor size and postoperative CEA in stage I colorectal cancer.

Patients And Methods: We analyzed a total of 305 consecutive stage I colorectal cancer patients who underwent a radical surgery at our Department. The patients were divided into low and high preoperative CEA groups, low and high preoperative CEA/tumor size groups, and low and high postoperative CEA groups according to the optimal cut-off values.
